The IESO also plays a vital enabling role – a role that will grow substantially in magnitude as new players enter the market and Ontario’s power system evolves. In 2010, the IESO has remained focused on maintaining reliability, preparing for future operations, efficiently managing the business, and effectively contributing to the development and implementation of the Green Energy and Green Economy Act, 2009 (GEGEA) and the Long-Term Energy Plan (LTEP).

By finding efficiencies, engaging in prudent spending and remaining focused on cost management, the IESO continued to demonstrate financial leadership. The IESO kept its fee unchanged for the second consecutive year and finished the year with a surplus. In fact, the 2010 usage fee of $0.822 per megawatt hour is almost 14 per cent lower than the rate charged in 2003.
